Seagate 600 Series 240GB SATA SSD

The Seagate 600 Series ST240HM000 is a 2.5-inch internal solid state drive with a 240GB capacity. It connects through a SATA III interface and uses 19nm MLC NAND flash memory. Sequential reads reach up to 530 MB/s and writes up to 440 MB/s. Random 4KB performance is rated at 80,000 read IOPS and 70,000 write IOPS.

Suits SATA laptops and desktops needing a 240GB

This drive fits 2.5-inch SATA bays in laptops and desktops where a 240GB MLC SSD is required. The 7mm height matches standard drive caddies. Systems that need an M.2 form factor or a different capacity should consider other models.

SATA III interface with 530 MB/s sequential read

The SATA III 6Gb/s host interface delivers up to 530 MB/s sequential read speed. This single specification determines whether the drive meets the throughput needs of the target system.

Questions about this item

How fast will the 530 MB/s sequential read feel when the drive is installed in a laptop?

The 530 MB/s read speed lets the operating system and large files load noticeably quicker than a mechanical drive, cutting boot and application launch times in typical use.

What does the SATA III 6 Gb/s interface limit in everyday operation?

The SATA III link caps maximum throughput at 6 Gb/s, so sustained transfers cannot exceed the drive's rated 530 MB/s read and 440 MB/s write even if the controller could go faster.

Will the 7 mm height fit a standard 2.5 inch bay in my notebook?

Yes, the 7.00 mm profile matches the common 2.5 inch laptop bay, and the 70.1 mm by 100.45 mm footprint aligns with standard mounting points.
